Virginia State Police said at a news conference Wednesday that two women and
one man were arrested Tuesday night in Alexandria.

Mersadies Shelton, 20, and Daniel Mathis, 18, are charged with the theft of Quick's
vehicle, which was found abandoned in a remote area in Louisa County on Monday.

Quick’s vehicle was reportedly used as a getaway car in an armed robbery and shooting
at around 7 p.m. Sunday in Louisa County, CBS affiliate WTVR reports. Mathis is charged in that armed robbery,
according to the station.

All three of the siblings are being held without bond.

The 45-year-old Quick was reported missing Saturday after he failed to show
up at the home of his estranged wife late Friday in Louisa County. She lives
about 20 miles from his Rockfish home and he texted her that he was on his way.

State police previously said two individuals were seen on surveillance
images with Quick's SUV in northern Virginia around 11:40 p.m. Friday. The next
day, the same two individuals were seen with Quick’s vehicle in Manassas,
according to the station.

It is unclear if any of the three arrested Tuesday night are the same individuals
captured in the surveillance images.

A reward for information in Quick’s case has risen to
$30,000. Virginia State Police say they are still heavily relying on the public
for information leading to the whereabouts of Quick.

Quick is a 24-year veteran of the Waynesboro Police Department’s
Police Reserve unit, Waynesboro Police Sgt. Brian Edwards told CBS News' Crimesider on Wednesday. He said Quick holds a volunteer position at
the department but is still considered a law enforcement officer.

Edwards
said Quick also worked with the Invista Corporation, a company which
specializes in the making of synthetic products, but was laid off a few
months ago.
